The best and most simple one, I think, is to enchant a pen or pencil. There was an AMAZING post that talked about rolling up pieces of paper with sigils or statements of intent written on them, and either taping them to pencils or inserting them into the tubes of pens. I just don’t know where it is to credit / source it.
Besides that, you can draw or carve sigils on almost any creative tool: a computer if you write or draw digitally, a drawing tablet, even a phone if you create art there - you can put the sigil directly as the phone’s background.
Spells:
[Charm Bag for Expressing Creativity]
[Creativity and Focus Spell]
[Creativity Chant]
[Creativity-Enhancing Sachet Spell]
[Creativity Jar] (kinda ingredient-based but kitchen herbs)
[Invoke Your Muse] (a little ingredient-based but there’s wiggle room)
[Little Spell for Inspiration] (for unfinished art)
[Spell for Creativity] (tw: gif)
[Spell for Creativity]
[Spell for Creativity/Inspiration]
[Wind Spell for Inspiration & Creativity]
There is also a creativity herbal blend that you can find [here].
Here are some things that you can use as substitutes in spells for creativity
